There were indelible images that captured the carnage like flies in amber—the planes crashing, the towers on fire, the falling men and women frozen in flight as they leapt to their deaths.

参考译文：这残杀的景象，就像琥珀中的苍蝇, 永远不能磨灭——飞机的撞击,双塔起火燃烧,向死亡深渊纵身跳去的男男女女刹那间定格空中一动不动的景象，历历在目。

请问老师，破折号后面的三大部分the planes crashing, the towers on fire, the falling men and women frozen in flight称作主句主语即indelible images的补语吗，用来解释说明，举例说明到底都有哪些景象，是这样吗？
